US and Iraqi forces have been carrying out an offensive against armed groups there for the past month, saying that al-Qaeda in Iraq has regrouped in the area after being pushed out of other parts of Iraq.

In another attack, a blast in the northern city of Tikrit has killed at least four people and wounded six more.

A police official says the bomb was planted in a car parked on a street used by local government officials going to work.
